What is the assembly of the cell?
Nowadays the concept of cell assembly is used loosely to describe a group of neurons that perform a given action or represent a given percept or concept in the brain. Typically, one thinks of the group as having strong internal synaptic interactions which set them apart from other groups of neurons.
How is a cell assembly formed?
Cell assemblies are groups of highly interconnected neurons . They emerge due to correlated neuronal activity, for instance induced by external inputs. Correlated activity, in turn, leads to modifications of the synaptic efficacies via synaptic plasticity.
What are the basic units of information processing in the theory of neuronal assemblies?
These neurons get together to form minicolumns which are perpendicularly disposed in relation to to the cortical surface. Each minicolumn connects to their neighbors , thus forming the so-called columns, which are the basic units of information processing.
What is cell assembly in psychology?
a group of neurons that are repeatedly active at the same time and develop as a single functional unit, which may become active when any of its constituent neurons is stimulated.
What do cell membranes consist mainly of?
Cell membranes are composed primarily of fatty-acid-based lipids and proteins. Membrane lipids are principally of two types, phospholipids and sterols (generally cholesterol).
Are mirror neurons?
Introduction. Mirror neurons are a class of neuron that modulate their activity both when an individual executes a specific motor act and when they observe the same or similar act performed by another individual.
What are hippocampal place cells?
Place cells are hippocampal neurons, typically from regions CA1 and CA3, that fire at a high rate whenever the animal is in a specific location in the environment, called the place field.
